and also adjacent one end, these bolts engaging ears a extending fromsegmental plates 5. These ears are twisted so as to lie in planesintersecting the planes occupied by the plates 5 so that, when the earsare clamped to one side of the bar 1, the plates 5 integral with theears overhang the bar. Obviously these plates can be swung about thebolts 3 so as to be brought to any desired angle relative to the bar. Bytightening the bolts the plates will be held against further adjustment.Each of the plates has a pivot receiving opening 6 and a standard 7 isconnected to each plate by means of a connecting bolt 8 extendingthrough the standard and the opening 6. Another bolt 9 is carried byeach standard 7 and is insertible into an arcuate slot 10 formed withinthe adjacent plate 5, the walls of the slot being corrugated so that,when bolt 9 is inserted into certain of the corrugations and tightened,it will securely hold the standards 7 against swinging movement relativeto the plates 5.

As heretofore stated the standards 7 of each attachment are adapted tobe connected to the frame B of the cultivator by means of the clamps C.These clamps can be adjusted so as to hold the standards 7 at any anglesdesired and said standards can be adjusted relative to the plates 5 andsaid plates can be shifted relative to the bar 1 so as to hold said barand the harrow teeth in any desired position relative to the cultivatorframe.
